If length is 0, the whole memory content from offset is stored.
The bytes-per-line argument specifies how many bytes to write on each line, defaulting to 16. Each line is written in little endian format, unless -b is specified, in which big endian format is used. An explicit offset is written on each line, unless -skip-offsets is specified, in which case only necessary offsets are written. If -skip-zeros is specified, lines with only zero data will not be written.
The command will fail if the destination file already exists, unless -overwrite is specified.
